As the leader of the German army, why did Hitler's nephew join the US Marine Corps?

Because he thought he could get a good job from his uncle, Hitler didn't take him as seriously as he expected. In addition, he immigrated to the United States and saw the evils of the Nazi Party, so he made up his mind to openly confront his uncle, joined the American army, and finally made many military achievements. Hitler's nephew is William, and William is also an ill-fated child. His father is Hitler's younger brother named alois. Alois married a beautiful woman in his hometown. He thought he could live happily together. Unfortunately, he is addicted to gambling. In order to gamble, he did not hesitate to sell his assets, and finally abandoned his wife and children and left Berlin alone. Soon, the First World War broke out. The war caused chaos and she lost contact with her son directly. Unable to keep in touch, both sides mistakenly thought that the other had died in the war. However, a few years later, when the war subsided, William's mother wrote to alois, only to find that the other party was still alive, so they discussed sending their son to Germany.

William grew up in England, and he couldn't adapt to life in a new country at all. The most important reason is that Germany was led by the Nazi Party at that time, and finally he chose to immigrate to the United States. After Hitler came to power, he found out that it was his uncle, so he returned to Germany and contacted Hitler, hoping that he could find himself a good job, but Hitler only arranged a job as a salesman. William must be very dissatisfied with this job. He asked his uncle to arrange another job for him, but Hitler ignored him. In a fit of pique, he left Germany and returned to America. After seeing the atrocities of the Nazi Party in America, he resolutely joined the American army, worked for the United States, and openly opposed his uncle. As a result, many people still think that if Hitler arranged a good job for him, he might choose to stand on the same side with Hitler, but the fact has happened and many things have not happened. It is impossible to verify the specific reason.
